FAB Intelligent Controller Series is a programmable controller launched by ARRAY, with the programming by FBD (Function Block Diagram) , which is simpler and easier to learn than the conventional PLC (ladder diagram and instruction). In the design concept of ARRAY FAB series products, traditional separated controller of PLC is combined with the writer on which the program can be written directly by using the function keys on the LCD front panel in order to reduce the cost and bring convenience to users. ARRAY FAB is very compact and light-weighted, especially suitable for internal installation usage. We recommend using a free software program and a cable to program the Fab as it is faster and easier. Free software Download.
